Acid–Base Cement Proportioned With Fly Ash and Oxalic Acid: Mechanisms, Performance, and Carbon Sequestration Potential

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 11, November 2026.
ABSTRACT Conventional Portland cement production is associated with substantial carbon emissions, while the utilization of off‐specification fly ash (FA), particularly high‐CaO FA, remains challenging due to its variable composition and limited reactivity.

Conversion of Spin‐Orbit‐Coupled Optical Vortices via Complex Coupling

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A four‐step Floquet protocol in a straight terahertz waveguide array uses metallic separators to selectively control interwaveguide coupling. The resulting angular‐momentum‐dependent coupling enables Floquet engineering of OAM states, giving rise to corner states, conversion between opposite total‐angular‐momentum states, and edge states.

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

Two‐Photon Grayscale Lithography (2GL) of High Mechanical and Optical Quality 3D Silica Glass Microstructures

open access: yesAdvanced Functional Materials, Volume 36, Issue 82, 12 October 2026.
Two‐photon grayscale lithography (2GL) enables high‐speed and precise 3D printing of thermolyzed silica glass microstructures with optical‐grade surface quality, high quality factors, and mechanical strength utilizing a custom‐made pre‐glass resist based on polyhedral oligomeric silsesquioxane (POSS) modified with a high‐sensitivity Norrish type II ...

The Cavitation Behavior of Inconel 690 Alloy

open access: yes, 2014
摘要 Inconel 690合金是現今工業界中用於高抗蝕性、高強度需求的環境中,相當重要的構件材料之一。然而在以Inconel 690合金為構件材料的設備中,除了有發生應力腐蝕(SCC)以及粒界應力腐蝕(IGSCC)之虞,窩蝕(cavitation)所造成的破壞也扮演著相當重要的角色,本研究便是針對Inconel 690合金的窩蝕(cavitation)破壞現象作一定點的連續觀察,進行窩蝕試驗前,先藉由金相試驗、硬度量測、X-ray繞射等鑑定分析Inconel 690合金之顯微組織及基本性質 ...

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, Volume 36, Issue 80, 5 October 2026.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.
